30kva Single Phase pole mounted step up oil power electric transformer 12KV To 208V
WINLEY’s Three Phase Pole Mounted Round Tank is designed for service in areas where three phase power is needed, but space is limited. It provides a cleaner looking service with lower installation cost than a bank of three single phase transformers. Triplex core/coil is the choice for serving electric motor loads especially with frequent motor starts.
Standard Feature
• Meets or exceeds current ANSI, IEEE, NEMA, RUS, and DOE standards as applicable
• Vertical triplex design
• Wet-process porcelain high-voltage bushings
(oil-filled at 125 kV BIL and above for reduced radio interference)
• Molded polymer or wet-process porcelain low-voltage bushings
• Tin-plated bronze terminals suitable for connection to copper or aluminum
• Low-voltage grounding provision
• Low-voltage ground strap
• Permanently stamped identification on internal secondary leads
• Visible cover ground connected to upper mounting bracket
• Tank grounding provisions
• Tank ground connector
• Automatic pressure relief valve for added safety
• Mineral oil with oxidation inhibitor
• Mild steel tank, cover and ring
• Corrosion-resistant cover-ring hardware
• Continuous-bead welding on lifting lugs and mounting brackets
for increased safety and corrosion resistance
• Recessed tank bottom for scuff protection
• Tough powder-paint finish for improved resistance to abrasion and corrosion
• 10 kV minimum cover and ring insulation
• KVA marking on tank
• Internal oil-level mark
• Laser-engraved aluminum nameplate
